issues like cost and ease of operation, cost of installation, cost and ease of maintenance, product quality, versatility, etc. The following presents a comparison of the two mill systems with reference to these issues. Grinding process The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball

mills, in the vertical roller mill the separator is inside the machine and only fine and rejected materials can be collected. The feed is calculated assuming a reasonable circulating load in the range of 8 – 12. The graph (Figure 2) illustrates the two Tromp Curves achieved with MA.G.A./VM 10 and without any grinding additive.

By changing the conventional 4-roller design to the 5-roller raw mill, a 10% down-sizing was achieved, and by changing the conventional 4-roller cement mill to the new 6-roller mill, a 20% down-sizing was achieved while maintaining the same grinding capacity in both cases. As just described, by changing to smaller, modular
